I just build a new system with the Asus P5N32-E SLI motherboard, Core2Duo E6400, 7950GT 512, 1Gb OCZ 5-5-12 DDR2-800, Philips 5.1 speakers.
I installed WinXP SP2 and did a full update from Microsoft.
I also installed the newest graphics and motherboard-chipset drivers from Nvidia and the soundcard drivers from the cd that came with the board (which are the latest).
When I do a soundtest using the installed sound panel of the ADI 1988B soundchip on the motherboard, all 5 speakers and subwoofer work perfectly.
But when I start any game that uses EAX (no matter what version) or A3D, the game reports that my machine does not support either and I am stuck with just 2 channel sound. (I tried Half Life, Half Life 2, Doom 3, Serious Sam, Serious Sam 2).
I checked out the ADI 1988B soundchip specifications on the ADI website, it states that it supports EAX 1.0, 2.0 and A3D.
I found that the ADI 1988B soundchip supports EAX and A3D in software, so it might be a driver problem, but a re-download of the drivers from the Asus website and multiple reinstalles of the drivers did nothing.
I only get 2 channel sound in games.
Anyone can offer any help?
thnx, Belgarath
